Frequency Control

Raymond D. Mindlin

Raymond D. Mindlin, Finch Professor Emeritus of Applied Science at Columbia University died on November 22, 1987 at the Dartmouth-Hitchcock Medical Center in Hanover, NH after a prolonged illness. He was 81 years old and resided in Grantham, NH at the time of his death. Professor Mindlin’s active and prolific scientific career spanned more than half a century, during which he made significant contributions in solid mechanics and the peripheral fields of acoustics and optics. As a consequence of this work he was a world renowned authority in both engineering and scientific fields and a consultant to government and industry. In particular, his very important work on the mathematical theory of the vibration of elastic plates and its impact on the field of frequency control is the reason for the inclusion of this remembrance in these proceedings.
